002 431 20 05 Mercedes-Benz Compatible Foot Brake Valve

What does a foot brake valve do?

This foot brake valve serves as a critical pneumatic component within the air brake system of heavy commercial vehicles. It functions by converting the driver's pedal force into regulated air pressure, which is then distributed to the wheel brakes to ensure precise and safe stopping performance. The valve is built with high-strength components to withstand rigorous heavy-duty operating conditions.

Vehicle compatibility and fitment

This specific unit is compatible with Mercedes-Benz vehicles. It is engineered to meet strict operational standards, featuring multiple connection points such as Port 4 (M12x1,5) and Port 12 (M16x1,5) to facilitate seamless integration into existing pneumatic lines.

Installation and maintenance

Technicians should verify the port configurations—including M16x1,5 on ports 21 and 22—during installation to ensure a leak-free connection. Maintaining a pressure equilibrium with a dominance of 0,3 BAR is essential for optimal pedal feel and response. Always check all fittings and air lines during routine maintenance intervals.

Troubleshooting and selection

Regular inspection of the valve assembly helps prevent pressure drops in the braking circuit. For fleet managers and workshop technicians, selecting components that align with original specifications ensures consistent braking performance across the entire vehicle fleet.

OE cross-reference
